甘肃省白银市青牛沟金矿地化特征及找矿方向

Geochemical Characteristics and Prospecting Direction of Qingniugou Gold Deposit in Baiyin City,Gansu Province

青牛沟金矿大地构造位置处于秦祁昆造山系-北祁连弧盆系-走廊南山岛弧,区内地层复杂,构造运动及岩浆活动强烈,成矿地质背景良好,成矿条件有利,矿产丰富。本文在总结了成矿地质背景、地球化学特征的基础上指出了找矿方向。

Qingniugou gold deposit is located in the Qinqi-Kun orogenic system-North Qilian arc basin system-Nanshan-island arc corridor.The stratigraphy in the area is complex,tectonic movement and magmatic activity are strong,metallogenic geological background is good,metallogenic conditions are favorable,and minerals are abundant.This paper summarizes the metallogenic geological background and geochemical characteristics,and points out the prospecting direction.
